 Hm, just a brief status report.
 
 The machine wedged in "normal operation" which doesn't really
 involve anything particularly "havy".  I think the trigger might
 have been the daily run; we monitor with collectd, and the load
 average increased to 5 and stayed at that (or higher) shortly
 after daily started.  Later the load increased to 15, and at
 the end CPU load increased significantly, but I suspect those
 processes were stuck in "tstile".
 
 Insight into what this might be and what to look for (e.g. via
 ddb, but also via "normal" logged-in methods) would be much
 appreciated.
 
 (I'm still 500km away, so it's been rebooted now.)
